I remember the secondary structure by visualizing it. Understand that primary structure is just the order of the amino acids. The tertiary structure is the 3dimensional configuration of the whole protein molecule with multiple interactions guiding its fold (disulfide bonds, ionic interactions, hydrogen bonds, van der walls). Secondary structure is a step towards the conformation of the protein where it is made up of either alpha-helices or beta-pleated sheets. The alpha helices look like a spiraling staircase while the beta-pleated sheets look like a repetition of long loops. These two structures hold itself by hydrogen bonds.

I'm pretty sure that these are the right answers. Anyways I hope I helped!
Answer:
American politician Elbridge Gerry, Vice President of the United States at the time of his death, who was Governor of Massachusetts.
Explanation:
The correct answer is A. Melting
Explanation:
Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.
This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.
